2022 Ford F-150 Lightning forced into dyno despite challenge

One 2022 Ford F-150 Lightning was tested independently dyno for the first time. The test showed that Ford’s all-electric pickup was close to factory rated output.

An extended range model was used in the test, made by the Texas Truck Show with support from manufacturer Dynocom. Ford rates that version at 580 hp and 775 pound-feet of torque, and the dyno shows 564.9 hp and 783.5 lb-ft at the wheel. That represents a 3% loss of horsepower from engine to wheels, but a bit more than published specs.

Brian Raupe, host of the Texas Truck Show, explained in an email to Engine Authority. With 145.5 inches at the hubs, the Lightning’s wheelbase is already beyond the limits of most accessible all-wheel-drive dynos testers. They tend to be used for smaller sports cars and max out at a 125-inch wheelbase.

With performance trucks, the solution is often to run rear-wheel drive on just one set of rollers. But that’s not an option with dual-engine Lightning. Dynocom has finally modified one of its DC-6000 dynos to accommodate the Lightning’s longer wheelbase. The DC-6000 uses a gearbox to synchronize two rollers. That’s more accurate than conventional belt systems, which are prone to tension, Raupe notes.

Dyno tests are also often based on engine rpm, but that’s not the right number for electric vehicles because of their instantaneous torque. Instead, Dynocom measured wheel speed. The final gear ratio is also needed to calculate, but Ford does not publish the ratio for Lightning. Using wheel speed and tire height, testers estimated the final drive to be 2:1 for each of the Lightning’s engines.

Final, lightning initially cuts power to less than 200 hp around 70 mph, then ramps back up to full power on the way to a top speed of 107 mph. This is due to excessive acceleration without real weight and wind resistance, Raupe said. Basically, the truck thinks something is wrong with it and has limited power. The workaround is to use software to apply additional resistance to the dyno rollers, simulating real world conditions.
